Originally known as Ryerson Bridge and was built to serve Ryerson's Mill. Mill burnt down and the name went with it. People then called it Benton Street Bridge.

WOW! This was an impressive bridge. It reminds me of the Bridgeport and Long Shoals bridges. Based on the photograph, it appears to be a Parker truss, not a Pennsylvania truss. Was there a span that was not visible in the photograph?
